WASHING-MACHINE.

SPECIFCA'IION forming part of Letters 'atent No.4 409,501, dated August 20, 1889.

Patented in Germany July 26, 1887, No. 42,550: in England May 23, 1888, No. 7,584; in France June 2,1888,1\T0. 185,152, and in Austria-Hungary September 22, 1888,l\l'o. 28,068

and No. 26,821.

T0 @ZZ 'whom it 71mg/ concerns Be it known that l, ALBERT RAMMOSER, a subject of the King of Prussia, Emperor of Germany, rcsidin at the city of Berlin, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improve.- ments in 1Vashiiig-Machines, (for which l have obtained a patent in Germany, No. 42,550, dated J'uly 2G, 1887; in France, No. 185,152, dated June 2, 1888; in England, No. 7,584, dated May 28, 1888, and in Austria-Hungary, No. 28,068 and No. 26,821, dated September 22, 1888,) of which the following is a specification.

This invention relates to a washing-inachine in which the clothes to be washed are laid upon a cloth or apron provided with transverse slats, and are operated upon by a roller having its surface provided with longitudinal slats or ribs.

rlhc invention will be understood on reference to the accompanying drawings, which represent three modifications in the construetion of the machine.

Figure 1 is"a longitudinal vertical section, and Fig. 2 a transverse vertical section, of the iirst modification. Fig. 8 is a longitudinal vertical section, and Fig. 4c a transverse vertical section, of the secondmodiiication. Fig. 5 is a vertical section, and Fig. G a top view, of the third modification. Fig. 7 is a vertical sectional view of a portion of Fig.

1n Figs. 1 and 2,A represents a water-tight tank or tub, in which is suspended a sacking or apron B, having its ends attached to the inner sides of the two opposite endsof the tub, near the top thereof, so that the intermediate portion will sag down nearly to the bottom of the tub. The apron B is composed of flexible bands or straps having attached thereto the slats or ribs a, which are of triangular form in their cross-section. Between the slats d and the straps b there may be interposed a sheet of network or of perforated india-rubber cloth.

The tub A is provided with a removable cover G, in the center of the upper side of which is a standard g, in which is pivoted an oscillating beam E, provided with a rigidlyattached handle or lever E.

To the ends of the beam E are attached bars c e, to the ends of which are pivoted the upper ends of rods F F. These rods pass bctween pairs of friction-rollers f, through the cover G, and into the tub A above thc apron B, and at their lower ends are journaled rollers D D, which have their surfaces provided with longitudinal slats or ribs, or, in lieu thereof, their surfaces may be grooved or fluted. A

At about the center of the interiofr of the tub A, under the apron B, a smooth roller C is journaled in elastic bearings, each of which consists of a block g on the upper end of a shank g2, working in lugs g3 on a plate secured to the side of the tub, with a spring d surrounding the shank between the block and the uppermost lug, so that said roller C is free to yield to any unusual pressure which may be brought to bear upon it.

The operation is as follows: The tub A being supplied with the proper quantity ofwater, the clothes to be washed are spread on the ribbed or slatted apron B, with sufficient wafer in the tub to cover them. Supposing the parts to be in the position shown in Fig. l-that is to say, with a portion of the apron nearly straight between the roller 3 and one end of the tub and the other portion of the apron between said roller and the opposite end of the tub sagged down nearly to the bottom of the tub, in which case the roller D is in the lowest portion of the apron and the roller D is above the nearly straight portion. Then the handle E is moved toward the right-hand side of the drawings, the positions of t-he parts will be reversed, the roller 1) and the sagged portion of the apron rise, and the roller D and the nearly straight portion of .the apron descend until they are as low as the opposite portion was previously. By means of this reciprocating vertical motion and the rotary motion of the rollers the clothes are thoroughly rubbed together and kneaded between the rollers and the apron and brought into contact with different portions of the water in. the tub, as their positions are constantly changed. It' the thickness of the layer of clothes should be too great, the elastiCally-journaled roller C will IOO yield to the pressure, and thereby prevent the clothes from being torn. The tub is provided with a faucet f2 for drawing' off the water. A

In the modification shown in Figs. 3 and 4: the oscillating beam and the bars and rods are dispensed with and the rollers D2 are weighted and operate by their, own gravity. The central roller C2 has its periphery provided with ribs d2, which engage with the under side of the apron B in the intervals between the ribs on said apron, Fig-7. One end of the shaft of the roller C2 is provided with a pinion R, which is engaged by a toothed segment Q, pivoted on the side of the tub, and provided with a handle E2 for oscillating it. When the handle is oscillated in either direction, a reciprocating rotary motion is imparted to the central roller C2, which inA turn imparts a reciprocating curvilinear motion to the apron B, causing it to alternately straighten out between the roller C2 and one side of the tub, and sag down between said roller and the opposite side of the tub, during which movements the rubbingrollers D2 are kept in contact with the clothes and the apron by their own gravity and rotate on their own axes, rising and lowering with the contiguous portions of the apron and the clothes, and rubbing the clothes between themselves and the apron as they so rotate and rise and fall. NVhen at theirhighest position, the rollers are prevented from rolling off the apron by means of partitions L, extending downward from the lid or cover G.

In the modification shown in Figs. 5 and 6 the apron B has its ends attached to two rollers H, journaled in the sides of the tub atopposite ends near the top, with the intermediate portion of the apron sagged down into the tub, and carrying a weighted ribbed rubbingroller D3 in the sagged portion. The shafts of the rollers ll carry toothed or sprocket wheels or pulleys K, around which passes an endless chain or belt J. One of the shafts also carries a pinion M, which is engaged by a pivoted toothed segment Q3, provided with a handle E3, for oscillating it. Vhen the handle E3 is oscillated in either direction, an intermittent curvilinear motion is imparted to the apron, so that its ends are alternately wound around one of the rollers and unwound from the other, while the weighted roller D3 remains in the sag near the bottom of the tub, where it rotates on its own axis, pressing and rubbing the clothes between itself and the apron in substantially the same manner as above described.

that I claim as new, and desire to secure by Letters Patent, is-

l. A washing-machine consisting of a tub and a flexible slatted or ribbed apron having its ends secured within the tub and forming a sag, and a weighted automatically-rotating ribbed roller working in the said sag of the apron, substantially as set forth.

2. A washing-machine provided with a flexible slatted or ribbed apron having its ends fastened to two rollers journaled at two opposite sides of the tub and provided with means for reciprocally rotating them, and with a weighted automatically-rotatingribbed roller working in the sag of the apron in the tub, whereby provision is made for washing the clothes between said apron and roller by the reciprocating curvilinear motion of the apron and the reciprocating rotary motion of the weighted roller, substantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
